Another interesting fractal is the Sierpinski Triangle, named after its inventor, the Polish mathematician Wacław Sierpiński (1882–1969). The order-0 Sierpinski Triangle is an equilateral triangle:

To create an order-N Sierpinski Triangle, you draw three Sierpinski Triangles of order N – 1, each of which has half the edge length of the original. Those three triangles are placed in the corners of the larger triangle, which means that the order-1 Sierpinski Triangle looks like this:
